Baroncelli M027.408.36.031.00— lug 20mm

The lug width is 20mm. This measurement is calculated by measuring the distance between the inner edges of the two lugs (spring bars) that anchor the strap to the case. A 20mm strap maintains correct proportional balance with the 40mm case without unwanted visual overflow.

It depends on intended use. For formal-classic contexts, we recommend dark brown alligator or vegetable-tanned leather, which develop a natural patina over time. For everyday versatility, a heavyweight cotton NATO. For warm climate or recreational water activities, dark grey FKM rubber. All available in 20mm size with secure deployante clasp.

Remove the watch from your wrist. Locate the spring bars (usually visible on the sides). Use a spring bar tool to compress the pin and slide the old strap outward. Insert the new strap by aligning the hole with the pin and allowing it to click into place. Simple operation, completed in 2-3 minutes without specialist tools.

Yes. Any strap with 20mm lug width is compatible with this reference. It is important that the strap has properly dimensioned holes or slots for standard spring bars and, preferably, a deployante clasp for security and comfort during extended wear.

A quality calf or alligator strap with vegetable tanning lasts an average of 4-7 years of daily use. Durability depends on environmental humidity, maintenance frequency (regular cleaning, light conditioning) and intensity of use. A rubber strap lasts 8-12 years. The spring bars can last indefinitely if not subjected to mechanical stress.
